Summary
Situated on the Occoquan River, this dam primarily serves a recreational purpose, providing a surface area of 200 acres for outdoor activities. Despite its significant hazard potential, the dam's condition was assessed as satisfactory during the last inspection in February 2019.
Owned by the local government and regulated by the Department of Conservation and Recreation, Lake Jackson Dam plays a crucial role in water resource management and climate resilience in the region. With state permitting, inspection, and enforcement in place, the dam ensures the safety of the surrounding community and the ecological balance of the Occoquan River. As climate change continues to impact water resources, the maintenance and monitoring of structures like Lake Jackson Dam become essential for sustainable development and disaster preparedness.
As enthusiasts of water resources and climate, understanding the significance of Lake Jackson Dam provides insight into the intersection of infrastructure, recreation, and environmental stewardship. With Robert J. Wittman representing the area in Congress, advocacy for responsible dam management and investment in resilience measures can help mitigate risks and ensure the long-term sustainability of this vital water resource. From recreation opportunities to flood risk reduction, Lake Jackson Dam stands as a symbol of the intricate relationship between humans and the natural world, highlighting the importance of proactive planning and collaboration in facing the challenges of a changing climate.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
